Question

我已经四处寻找答案了，我在这个网站和其他网站上看到了相关问题，但解决方案与我无关。我有一个应用程序，在我升级到IOS 4.2之前工作得很好。现在，该应用程序不会加载包含图像背景的视图，以及一组按钮和标签。该应用程序中有一个计时器，我可以确定计时器正在运行，因为从另一个帖子我可以证明在启动过程中执行了以下方法：

SELECTOR: application:handleOpenURL:
SELECTOR: application:openURL:sourceApplication:annotation:
SELECTOR: applicationDidReceiveMemoryWarning:
SELECTOR: applicationWillTerminate:
SELECTOR: applicationSignificantTimeChange:
SELECTOR: application:willChangeStatusBarOrientation:duration:
SELECTOR: application:didChangeStatusBarOrientation:
SELECTOR: application:willChangeStatusBarFrame:
SELECTOR: application:didChangeStatusBarFrame:
SELECTOR: application:deviceAccelerated:
SELECTOR: application:deviceChangedOrientation:
SELECTOR: applicationDidBecomeActive:
SELECTOR: applicationWillResignActive:
SELECTOR: applicationDidEnterBackground:
SELECTOR: applicationWillEnterForeground:
SELECTOR: applicationWillSuspend:
SELECTOR: application:didResumeWithOptions:
SELECTOR: application:didFinishLaunchingWithOptions:
SELECTOR: applicationDidFinishLaunching:
SELECTOR: createTimer

视图应该已加载。我没有收到任何错误消息。以下是我的applicationDidFinishLaunching：方法。

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

    // Override point for customization after app launch    

    // set instance variable for view controller
    viewController.pressNumberNext = TRUE;
    // reset total and last value
    viewController.userTotal = 0;

    // clear status text
    viewController.status.text = @"";


    // initalize the number of digits entered
    viewController.numberOfDigits = 0;

    // disable interaction with status area
    [viewController.status setUserInteractionEnabled:NO];

    // initialize items for the tokenizer
    viewController.endOfInput = [PKToken EOFToken];

    viewController.randomExpr = [[NSString alloc] initWithString:@""];

    // debugging flags
    viewController.debugSolution = false;       // debug flag to show solution under status


    // initialize the timer
    viewController.timeCount = MAXTIME;

    // timer should start running
    viewController.pauseTimer = false;

    // timer reset initialized
    viewController.timerNeedsReset = false;



    [window addSubview:viewController.view];

    [window makeKeyAndVisible];
}

非常感谢任何帮助。谢谢。

要检查的事项：

如何加载视图？通过一个笔尖，还是通过loadView中的代码？

在任何一种情况下，请检查视图的框架。在viewDidAppear中记录：动画：。
同时检查视图的alpha和隐藏属性。
你是否正在做任何奇怪的事情主窗口？是主窗口框架设置为的边界屏幕？是否设置了clipsToBounds 窗口？

升级到IOS 4.2后，未加载IPhone View
